Latest software updates

When I was in school I was diagnosed with a learning disability in reading. ThenI got to middle school and the library got Incredible Hulk every month. I devoured every back issue over an over again, just digging into every Peter David story I could get my hands on. His use of Greek mythology in his writing lead me to search out the original stories. I didn't care how hard the reading was, I struggled through it. As I was reading Hulk at school, my own comic collection was growing and I would read two or three comics before I went to bed, which lead to comic-based novels, and then eventually novels of all kinds.
Before I entered high school, I was tested again and my reading scores skyrocketed. In 8th grade, I had the vocabulary of a college student. My collecting has slowed since my kids have been born, but now they are digging into the same comics I bought at their age, and those same comics are making them better readers. Collectorz help me keep things in order as the kids explore.

Great app
App is great for cataloging, especially the ease of using the scanner. This app would get 5 stars if it added estimated worth of books. — nuzzbom on CLZ Comics

Very impressed
My cousin, brother, and I recently did a bagging and data entry party for our 3 comic collection's. We put well over 2500 comics into our databases combined and bagged over 5200 comics. We all use the Connect online software as well as the phone app. At one point, we had 1 Windows laptop, 2 MAC books, and one android phone all inputting comics into the same database at one time.
The fact we could all 3 access the same account at the same time was invaluable. This saved us many hours, perhaps as much as 30, being able to input comics simultaneously vs only having one device able to access the online acct at a time. Thank you for this.
The systems all worked flawlessly, we had no crashes, no hiccups, everything went as smoothly as possible and we were all very impressed with the job we performed and the job your software did and continues to do for us. Thank you for an outstanding program. — Christopher Sterner (USA) on Comic Collector

Keeping track of your collection
It's a great app for keeping track of your collection. With so many volumes to some of my Marvel favorites, it's nice to have a picture of the covers to help me out when I'm searching for comics at shows. — Scott Harms on CLZ Comics

I Discovered CLZ when i made a descision to start collecting comic books again. I had a small collection left from when i was a kid, it was something i did with my dad who passed away back in the early 2000's. After he died a big part of me was like "What's the point". Like many things at the time, it all kind of faded away.
So When i Made the Descision to collect again I Quickly realized i needed away to know what i already had. To This end, I found CLZ, it was affordable, and super easy to use, plus it was accessable on my phone which made it a great tool for when i hit the shops.
Then i realized I could also use it to Catlouge the Vinyl Records that got left to me. So now, I use it to catlouge both Comic and Vinyl collections, and in the process it helps me feel a bit closer to my father. — Kassidy Renault (USA) on Comic Collector

Near perfect app...
This is a great app. It takes away a lot of the “work” involved in the hobby. Easy to use for small and large collection. It’s worth every penny. — rs009c on CLZ Comics

Top notch
I love this app, and every update it just gets better! The only wish I have, is to add a price guide to it. Also, customer support is top notch. Had a problem with my app and PC connecting and they solved it quickly! Thank you so much for this app! — Rod Freund on CLZ Comics

Comics Collector from Collectorz.com
I have been using the Comics Collector sw for about 10 years to increase my happiness and joy with my collection. I had always wanted to organise my collection so that all the relevant publisher, creator information and the covers would be easily located and sorted. An attemptt to create a spreadsheet that would do this for me gave me the pleasure of a deep dive into my collection and a severe back ache from sitting with my laptop on a broken sofa. I came accross Comics Collector and tried it out and it has been contributing greatly to my happiness ever since.
Sometime I put on the cover flow and just roam through my collection, each cover is a vivid moment that reminds me why I love comics. I have organised and re-organised my collection as I have changed my mind about what is the best way to group the comics. I can do this easily, the interfaces are clear and natural. Comics Collector has increased my pleasure in my comics collection hugely by capturing what I wanted to be able to do with careful attention to detail and first rate customer care. The updates are seamless, in fact they give a good name to software updates...
As I have been writing this I have been thinking about why Comic Collector is so good and I realised that it has been written for collectors, it makes capturing the many details about comics easy, showing off the covers easy, sorting and re sorting the collection easy. It is a brilliant tool that really allows me reach into the detail of my comics and relish them. — Conor Carton (USA) on Comic Collector

My collection under control and in numeric order
I've been using CLZ for my comics for 3 or 4 years now and had been doing things manually before that. My collection currently exceeds 18,000 books and I've been collecting for decades.
When I started collecting, I kept a hand written ledger of my books so I wouldn't spend my hard earned cash on duplicates. When Lotus 123 came on in '83 (does anyone actually remember Lotus 123?), I procured a copy and transferred my entire collection to a spreadsheet. Awesome. My first actual backup, besides my hand written book, was to a 5.25" disk.
After Lotus was crushed by Microsoft, everything had to go to Excel. I believe that most everyone has a horror story regarding hardware and mine was a crashed hard drive in '96 that ate my data and left me with just a 3.5" disk that contained the backup of my comic collection. Needless to say, the disk turned out to have been corrupted at some point and I was back to ground zero.
With all of the writing and keyboarding over the years, I'm pretty sure I'm patient #0 for Carpel Tunnel Syndrome. It was then I decided the Comic Books gods did not want me to know what I had in my collection so that Marvel, DC, Charlton, and the rest could get more of my hard earned cash since I'd likely be buying duplicates at one point or another.
It wasn't until I found CLZ 3 or 4 years ago that I started to catalog my collection again. This has done many things:
It uncovered more than 3,000 duplicates (hard earned cash out the window. My ex-wife was angry about that tidbit).
It allowed me to actually get my collection under control and in numeric order in their boxes (currently 170+ short boxes and a couple of long boxes
The initial time of entering them into CLZ was considerable, but necessary. Now when I buy 2 or 300 books at a show, it's so easy to get them into the system.
It allows me to travel to Comic-cons and bring my collection with me so when I'm spending my hard earned dollars, I'm not buying dupes. (something my current wife appreciates)
I finally know exactly what I have and I know it's safe from most any tech disaster that I might have.
Most important in all of this? It provides a safe place for my database. Something I didn't have for 40 years.
I forget what I paid for this program when I bought it, but it's been worth every penny of my hard earned dollars since. — James White (USA) on Comic Collector

Very good app
Very good app once purchased. Only thing missing is an integrated Overstreet grading scale (Fine, very fine, near mint etc.) in wich one could select his books rating. Ex.: Near Mint 9.2. Other than that, fabulous app for a collector! — Simon Marcotte on CLZ Comics

Your product goes everywhere I go
I have collected comics on and off throughout my life, starting at the age of 6 (when Mom would "bribe" me with 50 cents if I was good in church--hey, I could buy TWO books at the newsstand then!) and all the way now through my 54th birthday. During that time, like a lot of hobbyists, I have had 'hot' times where I've really been into my collection, and others when I've cooled down...
I now do a yearly show or two. Because of all of that, it would be almost impossible for me to remember how many books I have in my collection (6712) vs how many are in my "sale boxes" (1200) without CLZ. Your product goes everywhere I go on my phone--putting an end to the "I wonder if I have that?" stuff that goes on at dollar bins.
I am very thankful for your product and everything you guys do for the collecting community! — Mike Boyd (USA) on Comic Collector

CLZ has made my life so easy
I am a 56 year old lifelong comic fan...and still collecting. I have about 15,000 comics and before discovering CLZ I used a looseleaf notebook to add all my comics. Needless to say, this turned into a ripped, and disorganized mess very quickly. Of course, I was only able to catalog the title and the issues that I owned and I could never see the critical data or the comic covers.
I constantly use CLZ, not only for data entry, but to view my lovely collection. I also love the way that CLZ breaks down the stats to my collection and gives me possible value of the collection. The software support and updates are spectacular!! — Scott Farren (USA) on Comic Collector
